Click the page tab watermark to display the drawing window, and click Insert Text Box. Here you can enter any text that you want to appear behind your foreground page, for example, "draft" or "confidential." You can resize and rotate the text to position so that it's visible when you view the foreground page.

The new background page named watermark is automatically assigned to the page that you had open and your watermark appears behind any shapes on the foreground page.

Edit a background or watermark

You can edit the shapes on a background page only by going to the background page in the diagram and editing it directly. You can’t edit the shapes if you’re looking at a foreground page, even though you can see the shapes that are on the background page.

Click the background page tab to display that background in the drawing window.
